Functional Description
The BE1-GPS100 Generator Protection System is an
economical, microprocessor based, multifunction system that
provides a comprehensive mix of protective functions to detect
generator faults and abnormal operating conditions along with
control and metering functions in an integrated system. Two
Basler Electric half-rack units can be dovetailed together to
mount in a standard 19” equipment rack with no special
mounting hardware. The innovative half-rack case is fully
drawout with current circuit shorting provisions. The system
includes:
• Fuse loss detection • Breaker failure protection
• Three phase, ground, and negative • Voltage protection
sequence overcurrent protection • Loss of excitation
• Forward and reverse power protection
protection • Frequency protection
• Sync check protection • Volts per hertz protection
Application
The BE1-GPS100 Generator Protection System can be
applied in any generator protection application. Its unique
capabilities make it ideally suited for applications:
• Requiring the flexibility provided by wide settings
ranges, multiple settings groups, multiple coordination
curves, and an extremely versatile programmable logic,
in one unit.
• Requiring the economy and space savings provided by a
multifunction unit that can provide all of the protection,
control, metering, and local and remote indication
functions required in many typical units.
• Where space constraints dictate protection systems with
small size and minimal behind-panel projection for
substation modernization projects.
• Where protection redundancy is provided by having
differential relaying in an independent protective relaying
package.
• Requiring communications and protocol support.
• Where drawout construction is desirable.
• Requiring high accuracy across a wide frequency range.
